SPECIFICATION forming part of Letters Patent N o. 663,227, dated December 4, 1900.

Application led June 13, 1900. Serial No. 20,142. (No modelo The invention relates to improvementsfjn carts and other vehicles, and pertains more? particularly to the means hereinafter described for mounting the cart-body upon the shafts or booms. 1

The invention consists of the novel con structions, arrangements, and combinations of parts hereinafter described, and particularly pointed out in the claims. i

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation, partly in section and partly broken away, ot' a cart constructed in accordance with and embodying the invention. Fig. 2 is an enlarged side elevation, partly in section, of a portion of same. Fig. 3 is a vertical transverse section of same on the dotted line 3 3 of Fig. 2. Fig. 4 is a detached bottom View of the cap which tits upon the upper central portion oi" the spring, and Fig. 5 is a detached top view of the lower plate which cooperates with the cap shown in Fig. 4 in inclosing the central portion or" the spring.

In the drawings, designates the usual cart-wheels, 11 the body of the cart or Vehicle, and 12 one of the shafts or booms of the cart.

Upon opposite sides ofthe cart-body 11 arev a spring 15 and cap 16 thereon, said cap hav.

ing above said spring the circular opening or bearing 17 to receive the trunnion 14, connected with the cart-body, whereby said springs 15 will comprise a suitable number of leaves, as shown, and at one end the lower leaves of said spring will be shaped to form the eye 21,1.hrough which the bolt 2() at the said end of the spring will pass, and at the other end of the spring 15 the lower leaves thereof will be bent to form the hook 22 to pass upon the bolt 20 at that end ofthe spring, as shown at t-he right-hand side ot' Fig. 2. The eye 21 at one end of t-he spring 15 serves to hold that'end of the spring in rigid position, while the hook 22 at the other end of the spring permits of the spring having at its hook end a longitudinal sliding motion under the variations of the load which may come upon it. The hook formation-22 at one end of the spring 15 cooperates with the bolt 20 in serving as a stop limiting the inward motion ot the spring, but permits said spring to have an endWise-sliding motion between the ears 19 at the right-hand end of the plate 18. The plate 1S, in addition to being provided with the ears 19 and bolts 20, possesses along its longitudinal edges the ribs 23, which strengthen the plate 18. The plate 1S carries the spring `15, and said spring Y15 when in use exerts all of its wear or frictional action against said plate 1S and has no prejudicial effect vupon the shafts or booms 12. It does not make any difference at which end of the spring 15 the hook formation 12 is located, but in the present instance the hook formation 22 is at that end of the spring 15 adjacent to the rear end of the shafts or booms l2.

The middle portions of the leaves of the springs 15 are connected together by means of the bolts 24, and said portions of the leaves of the spring l5 are also bound together by the cap 16,1ower plate 25, and U-shaped bolts 26 26. The plate 25 is a simple strip of `metal having its ends turned slightly downward, as shown in Fig. 2, and having at its central portion the recess 27 to accomn1odate the head of the bolt 24, and said plate IOO is of substantially the same width as the spring 15 and practically coextensive in length with the cap 16. The cap 16 is of cast metal and fits snugly down upon the spring 15, and said cap 16 at its apex is furnished with the aperture 17 for the trunnion 14,

outward from the depending sides of the cap 16 and receive the vertical members of the U-shaped bolts 26, as shown in Fig. 1. The bolts 26 have nuts applied upon their upper ends, extending upward through the tubular sleeves 28, and the bend or loop portions of said bolts 28extend transversely below the plate 25 and spring 15 andvbind said plate 25 against the lower surfaces of the said spring. In order to as far as possible avoid all noise from the cart, I provide intermediate the lower surfaces of the cap 16 and the adjacent upper surface of the spring 15 a strip of rubber or other suitable material29, which extends the full length of the cap 16 and passes over the nut on the bolt 24, as shown in Fig. 2. The lower surface of the cap 16, directly below the bearing-aperture 17, is recessed, as illustrated in Figs. 2, 3,

and 4, to accommodate the nut on the upper end of the bolt 24. It will appear obvious that when the cap 16, plate 25, and bolts 26 are applied upon the spring l5 they very materially increase the strength of said spring and afford a rigid support forthe trunnions 14 on the cart-body. By tightening the nuts on the upper ends of the bolts 26 the plate 25 and cap 1G maybe drawntoward one another and against the upper and lower surfaces of the springs with all of the firmness and rigidity that could be desired. The recess 30 in the cap 16 and the recess 27 in the plate 25, respectively receiving the nut and the head of the bolt 24, aid in preventing said cap and plate from having any sliding motion upon the spring 15, and said recessesv also facilitate the proper initial placing of said cap and plate upon said spring. The bolts 26 firmly clamp the cap 16 and plate 25 upon the spring and the downwardly-turned ends of the plate 25 aid in preventing any sliding of said plate from position during the use of the cart. The tubular ears 28 on the cap 16 maintain the proper position of the bolts 26, since said ears retain the vertical members of said bolts in proper vertical position.

The'plate 18 is secured upon the shafts or booms12 by means of the bolts 31, 32, and 33, the said bolts also passing through the plate 34, applied to the lower side of the shafts or booms 12, as indicated in Fig. 2. The bolts 31 at their lower portions are connected .by the plate 35, and said plate, with the lower portion of the bolts 31, together with the recess 36, formed in said plate 34, constitute a frame for the end of the axle 37, upon which the cart-wheels 10 are mounted. The bolts 32 pass through the plate 34, shaft or booln 12, and plate 18 and aid in binding the plates 18 and 34 upon the upper and lower surfaces of theshaft 12, greatly strengthening the structure and preventing the bolts 32 from having any special wear or influence upon said shafts. The bolt 33 in the present instance passes through the shaft 12 and plate 18. The plate 34 at each side of the cart is formed with a recess 38 to receive the end of a transverse har 39, said bar 39 extending transversely across and connecting the shafts 12' and having its ends secured within the recess 38 of the plates 34 by means of bolts 40, which extend upward through the plates 34, shafts 12, and plates 18. The bolts 40, while securing the transverse bar 39 in position, also aid in binding the plates 34 and 'plates 18 upon the shaft 12.

By means of the construction hereinbefore dghribed I produce a very efficient, simple, and durable cart or vehicle and one which can withstand substantially any reasonable amount of abuse witho utinju ry tothe springs 15. The construction is also one which in itself preserves the springs 15 from breakage and avoids the result of any accident'which might occur by the breakage of the springs at the bolt 24, which is the only point at which the springs are in any way cut or weakened. Should the springs break at the bolt 24, the cap 16, plate 25, and bolts 26 would have the eect of keepingthe springs together at their middle portions until the cart could reach a proper destination for its repair. My experience is, however, that the springs 15, mounted in the manner and provided with the device hereinbefore described, are not at all liable to breakage, but are of great durability and add very much to the utility and longevity of the cart.

When the invention is applied to a dumpingcart, the booms 1,2 will extend forward to a sufficient extent to constitute the shafts for the horse; butin other classes of vehicles the booms 12 will constitute a part of the bed or frame forming, with the wheels and axles, the running-gear.
